20130211 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a bone marrow shows low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia? See Discussion.

Physician note: Bone marrow shows 10% involvement with low grade lymphoma. Assessment: Low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia.

The multiple primaries calculator indicates two primaries are to be reported. However, the physician stated that Waldenstrom's macroglobulinemia is another name for this patient's lymphoma.

There were no enlarged lymph nodes seen on the CT scan. The proposed treatment for this patient is Rituxan for the macroglobulinemia.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Per Rule M2, this is a single primary because there is a single histology. The bone marrow initially showed a non-specific B-cell lymphoma. WM is a type of B-cell neoplasm. After immunophenotyping, a more specific histologic diagnosis of WM was made. In this case a single histology (WM) is diagnosed by the definitive diagnostic method (serum paraprotein demonstrating IgM), so it accessioned as a single primary.

Per PH16, code the histology to 9761/3 [Waldenstrom Macroglobulinemia (WM)] and the primary site to C420 [blood].

20130042 Reportability--Heme & Lymphoid Neoplasms: Is follicular lymphoma in situ reportable? See Discussion.

Parotid mass and intraparotid lymph node biopsy: Follicular lymphoma in situ (see note).

Note: The morphologic findings in conjunction with the results of immunohistochemical stains demonstrate focal follicular lymphoma in situ in a background of reactive follicular hyperplasia. Cytogenetic studies on the parotid mass demonstrated a normal karyotype. FISH analysis for BCL2 and BCL6 gene rearrangements has been requested and will be reported separately.

Per the Note under Case Reportability Instructions Rule 3 in the Hematopoietic and Lymphoid Neoplasm Manual, do not report in situ [/2] lymphomas. 2013
20130129 Histology--Heme & Lymphoid Neoplasms: How is histology coded for a diagnosis of composite lymphoma (follicular lymphoma and small lymphocytic lymphoma, BCL-2 positive)?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the histology to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL)] per Rule PH15. Code the histology to the non-Hodgkin lymphoma (NHL) with the numerically highest ICD-O-3 code when two or more NHLs are present in the same present in the same lymph node(s) or lymph node region(s), tissue(s), organ(s), or bone marrow. Both follicular lymphoma [9690/3] and SLL [9823/3] are types of NHL. Therefore, the histology is coded to 9823/3.

This composite histology represents a single primary per Rule M4. The rule states to abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s).

20130173 Histology/Primary site--Heme & Lymphoid Neoplasms: How is the primary site and histology coded when a bladder biopsy reveals myeloid sarcoma and a simultaneously performed bone marrow biopsy demonstrates acute myeloid leukemia? See Discussion.

12/22/11 Bladder biopsy: myeloid sarcoma,

12/22/11 Bone marrow biopsy: acute myeloid leukemia.

Presenting symptoms were urological with three month history of painful hematuria and hydronephrosis with solid mass of bladder.

Prior to biopsy hem/onc states bladder mass of unknown pathology. CBC revealed peripheral blasts and Auer rods -- presumed diagnosis of acute myeloid leukemia (AML). No statement from physician as to where disease originated.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Per Rule M3, abstract a single primary when a sarcoma (myeloid sarcoma) is diagnosed either simultaneously or after a leukemia of the same lineage (acute myeloid leukemia). Per the notes for Rule M3, the sarcoma is a solid manifestation of the associate leukemia.

Per PH10, code the histology to 9861/3 [acute myeloid leukemia] and the primary site to C421 [bone marrow]. PH10 states one is to code the primary site bone marrow (C421) and code the histology acute myeloid leukemia, NOS (9861/3) or any of the specific AML histologies (9840/3, 9865/3-9867/3, 9869/3-9874/3, 9891/3, 9895/3-9898/3, 9910/3, 9911/3 and 9931/3) when the diagnosis is myeloid sarcoma (9930/3) AND there is a simultaneous or previous diagnosis of acute myeloid leukemia.

20130008 Primary site--Kidney, renal pelvis: Should primary site be coded C809 [unknown] or C649 [kidney] when a patient is diagnosed with renal cell carcinoma in a transplanted kidney? Code the primary site to C649 [kidney]. Per the SEER Manual, code the site where the neoplasm originated. There are no separate instructions for coding primary site for transplanted organs. This patient's renal cell carcinoma originated in the kidney [C649]. 2013
20130111 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2008 diagnosis of extralymphatic follicular lymphoma in the breast is subsequently diagnosed in 2011 with ocular follicular lymphoma? See Discussion.

The patient was diagnosed with follicular lymphoma in the breast in 2008. Per notes, there was no evidence of disease again until 2011 when the patient presented with ocular lymphoma. The physician stated this was part of the same disease process as the prior breast diagnosis. The bone marrow was not involved in either case.

Is this a single primary (recurrence) of follicular lymphoma? Or are these multiple primaries because they arise in different extralymphatic sites?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Accession a single primary, follicular lymphoma [9690/3] of the breast diagnosed in 2008 per Rule M2.

Accession a single primary when there is a single histology. This is a recurrence of the patient's 2008 follicular lymphoma.

20130222 MP/H Rules/Histology--Bladder: How is the histology coded for a single bladder tumor showing invasive urothelial carcinoma with extensive divergent differentiation including small cell carcinoma, micropapillary carcinoma, and squamous cell carcinoma features? See Discussion. MP/H rules seem to lead to Rule H8 which indicates that one use the numerically higher ICD-O-3 code. If one applies Rule H8, the histology is coded to 8131/3 [micropapillary urothelial carcinoma]. That would ignore the small cell carcinoma, which seems prognostically more significant. Code the histology to 8045/3 [mixed small cell carcinoma], a combination of small cell with other types of carcinoma. There is currently no rule in the urinary site MP/H Rules for this combination of histologies. This will be included in the next revision of the MP/H Rules. 2013
20130106 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2009 diagnosed Hodgkin lymphoma, nodular sclerosis type is treated and subsequently presents in 2010 with the same diagnosis? See Discussion.

2009 diagnosis of Hodgkin lymphoma, nodular sclerosis type involved the superior mediastinal nodes, AP window nodes, bilateral axillary nodes and pulmonary nodules. The patient received chemotherapy and went into remission.

Patient presents in 2010 with Hodgkin lymphoma, nodular sclerosing type in the superior mediastinum.

Does timing play any part in determining if this reported as one or two primaries? There is no timing rule in the Heme Manual.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Accession a single primary, Hodgkin lymphoma, nodular sclerosis type [9663/3] diagnosed in 2009 per Rule M2.

Accession a single primary when there is a single histology. Note 2 for Rule M2 indicates timing is not relevant. This is disease progression or recurrence and not a new primary.

20130202 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported when a solitary plasmacytoma diagnosed in 2010 (T spine) is followed by another solitary plasmacytoma (L spine, different primary site) in 2013? See Discussion.

In the Heme Manual it indicates one is to abstract a second primary when a solitary plasmacytoma (chronic) is followed by a plasma cell myeloma (acute) greater than 21 days after the chronic diagnosis.

The Heme Manual does not indicate what to do when a solitary plasmacytoma diagnosed in 2010 (T spine) is followed by another solitary plasmacytoma (L spine, different primary site) in 2013. The physician specifically stated the patient does not have multiple myeloma. Is this case one or two primaries?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Per Rule M2, this is a single primary. According to Rule M2, the single histology is always the single primary.
